User guide

Protein[DS] allows user to play with up to 4 "modules" at the same time.

Title screen:

The is the screen which appears at startup.

DScratch module:

This module is kind of a turntable, it lets you play with wav or recorded samples, or even live audio from microphone: you can scratch, pitch, apply effects, cut volume etc. This is the only really advanced module for now.

DSamples module:

For the moment, this module only lets you play a wav sample by hitting a key. Anyway, it's the next module I'll be working fully on, to create an advanced sampler.

DSControl module:

This is a basic implementation of a MIDI controller using both the touchscreen for MIDI cc, and keypad for MIDI notes.

Sample-Recorder tool:

This tool records samples from the DS built-in microphone. The total recording time is set to 20 seconds. Recorded samples can be recorded to disk (cf Configuration/Setup Save) .

Sample-Browser tool:

This tool ables you to browse through your samples-directory (cf Tips), preview a sample, and finally load one within the caller module.

Controls

Uses Stylus.

Start - access to the main options, state save, main config.

Select - choose a module

D-pad - choose one of the four modules

L/R - back to any module

Known issues

Waiting for a new implementation, using DualScreen mode only allows 30fps, plus the two screens may flicker - deactivating DualScreen gives you 60fps, which is a lot better for scratching!

DScratch may not be able to play big files backward: crossing the end/beginning sample's edge backward way lock the audio engine due to a too long file access. It seems like NDS filesystem is too slow when seeking point is too far.

Midi may fail to init when using DSMidiWifi on some computers (only tested on Mac for the moment, other os reports are welcome).

Audio engine may lock at some point while using MIDI.
